| 摘 要： | We study the effect of Landau--Zener (LZ) tunneling causedby the varying sweeping rate of the external field, and solve theproblem about the LZ tunneling rate among many levels. The LZtunneling rate is essentially changed by the unsteady variation ofthe time-dependent sweeping field and is different from the steadilyvarying sweeping field, which makes the particles in lower statestransit periodically to upper states within a finite time.
